Diagnostic Efficacy of Signal Intensity Ratio and Apparent Diffusion Coefficient Measurements in Differentiating Cerebellopontine Angle Meningioma and Schwannoma
Abstract:Objective: To investigate the efficacy of Signal Intensity Ratio (SIR) measurements of T2-weighted imaging (T2WI) and Apparent Diffusion Coefficient (ADC) values of ADC mapping in the differentiation of schwannomas and meningiomas originating from the CPA.
Materials and Methods:A total of 30 patients who were pathologically diagnosed (16 meningiomas, 14 VS) were included in this retrospective study. SIR was calculated by proportioning regions of interests (ROIs) measurements of solid regions of the tumor and o… Show more
